A person in a wheelchair exerts a force of 25 newtons to go up a ramp that is 10 meters long. The weight of the person and wheel

Natali [406]

The work output of the procedure is given as,

$W_O=wh$

Substitute the known values,

$\begin{gathered} W_O=(60\text{ N)(3 m)(}\frac{1\text{ J}}{1\text{ Nm}}) \\ =180\text{ J} \end{gathered}$

Thus, the work output is 180 J.

The work input of the procedure is,

$W_i=Fd$

Substitute the known values,

$\begin{gathered} W_i=(25\text{ N)(10 m)(}\frac{1\text{ J}}{1\text{ Nm}}) \\ =250\text{ J} \end{gathered}$

Thus, the work input is 250 J.

The efficiency of the person is given as,

$e=\frac{W_O}{W_i}$

Substitute the known values,

$\begin{gathered} e=\frac{180\text{ J}}{250\text{ J}} \\ =0.72 \end{gathered}$

Thus, the efficiency of person is 0.72 or 72%.

Compared to the size and density of Earth, the Moon has a A. smaller diameter and lower density B. smaller diameter and higher d

MrRa [10]

Answer:

(a) Moon has smaller diameter and lower density than earth

Explanation:

Moon has smaller diameter than earth earth has a diameter of 12742 km whereas moon has a diameter of 3474.21 km

So for density density is given by $density=\frac{mass}{volume}$

From the relation we can see that density is dependent on mass and volume directly proportional to mass and inversely proportional to diameter

But in case of earth and moon mass is more dominating than volume so density is less for moon than earth
